re-launch Windows 8 app in c#

Consider an ordinary Windows 8+ app - in my case a Unity3D build. Call the app Teste.

This is running on a captive computer which has no other purpose and there are no security concerns, any Windows settings can be used.

I want Teste to be able to quit itself and then indeed launch itself again.

Currently we do (this), which works fantastically

System.Diagnostics.Process.Start( "shutdown", "/r /t 0" );

and of course have Teste launch on startup of the box using startup items. {So, Windows+R, shell:Common Startup, add a shortcut.}

However, is there a way to have Teste just quit itself and then restart itself?
